NAME
       xdpyinfo - display information utility for X

SYNOPSIS
       xdpyinfo [-display displayname] [-queryExtensions] [-ext extension-name]

DESCRIPTION
       Xdpyinfo  is a utility for displaying information about an X server.  It is used to examine the capabilities of a server,
       the predefined values for various parameters used in communicating between clients and  the  server,  and  the  different
       types of screens and visuals that are available.

       By default, numeric information (opcode, base event, base error) about protocol extensions is not displayed.  This infor-
       mation can be obtained with the -queryExtensions option.  Use of this option on servers that dynamically load  extensions
       will likely cause all possible extensions to be loaded, which can be slow and can consume significant server resources.

       Detailed  information  about a particular extension is displayed with the -ext extensionName option.  If extensionName is
       all, information about all extensions supported by both xdpyinfo and the server is displayed.

ENVIRONMENT
       DISPLAY To get the default host, display number, and screen.
